As an example, excess heat of 1MW delivered for the majority of the year generates income amounting to SEK 1.5 million.

Energy prices, delivery temperatures and capacity requirements are published on Open District Heating’s website by 4pm the day prior to delivery, and are based on the projected outdoor temperature for the coming day. If a supplier has an On Demand agreement, the supplier is required to deliver capacity if requested to do so. If a supplier has an Open Spot contract, the supplier chooses whether to accept a request and supply heat under the applicable, published conditions. Payments to suppliers for delivered heat are made on a monthly basis.

Heat that is delivered to Stockholm Exergi’s system becomes district heating that is used for heating and hot water for the city’s homes and offices.

All businesses that continually generate excess heat, and which are located adjacent to Stockholm Exergi’s district heating network in the Stockholm region, can sell their energy to us.

For us, Open District Heating is the answer to a number of challenges. Firstly, competition for raw materials and fuel is becoming increasingly fierce. This alone justifies large-scale energy recovery. Furthermore, we need to continually improve energy and fuel efficiency.

Secondly: climate change, in combination with financial incentives and higher fuel prices, makes it both more commercially risky and environmentally unsustainable to not entirely phase out fossil fuels as a source for heating in the long-term. We need to find alternatives that can replace the residual use of fuel oil and coal.

Thirdly: the development and renewal of heating and cooling distribution networks will become increasingly expensive. We need to find smarter ways to use our networks.

And lastly: uncertainty and fluctuations in energy markets is increasing at the same rate as the share of renewable energy increases. We see a considerable commercial and environmental value in mitigating these fluctuations with flexible and multifaceted production.

At Stockholm Exergi, we produce and supply district heating and cooling to our customers in Stockholm so that they have warm housing and hot water. Historically, we have primarily been a production and distribution company. With Open District Heating, we’re shifting from the production and distribution of heat and cold to opening up our network for trading in heat and cold. Everyone that has excess heat can now sell it to us. Together with new trading partners in and around Stockholm, we are creating value. Open District Heating will provide a more effective, more profitable, and at the same time more sustainable energy system in Stockholm.

District heating is supplied to properties in the form of water that is heated centrally. Hot water is transported in a system of well-insulated, high-pressure pipes. The water is between 65 and 120 degrees, depending on the time of year and weather, and is supplied to substations in each property. These units are fitted with heat pumps that use the hot water to heat buildings’ radiators and hot water supply.

District heating currently supplies half of Sweden’s total heating requirement and it continues to expand. Fortum is the country’s leading supplier of district heating. Nearly 9,000GWh of heat in Fortum’s wholly and partly owned district heating plants in the Stockholm area.

Stockholm Exergi supplies some 90 percent of greater Stockholm’s heating needs with district heating.
